Hello Richard,

Thanks for presenting your view on these issues.  I specially
appreciate the POV about the semicolon being an operator.  Having the
optional semicolon at the front seems to work equally well indeed.

The situation I refer to is indeed swapping entries (copy & paste) and
introducing new elements at the end without having to touch the
previous line.

Some of it may indeed be automated with a good editor, and some things
like unifying comprehensions are a bit trickier.

I don't actually suffer too much.  Partly because I just get used to
it, and partly because things will improve over time one way or the
other.  In this specific case I'm just adding to the statistics so
that the stakeholders here have some data to work with.  I'm pretty
sure I'm not pointing out anything that they didn't already have in
the back of their minds.

Thanks for taking the time to bring these details up.
